Why is Sumitomo Chemi. falling/rising?

As of 07-Nov, Sumitomo Chemical India Ltd is experiencing a decline in its stock price, currently at 476.30, reflecting a decrease of 3.95 points or 0.82%. The stock has underperformed its sector today by 0.86% and has been on a downward trend for the past three days, accumulating a total decline of 6.42%. Over the past week, the stock has fallen by 5.20%, and its performance over the last month shows a significant drop of 10.85%. Despite a high management efficiency indicated by a return on equity (ROE) of 15.53% and a low debt-to-equity ratio, the company has shown poor long-term growth, with net sales increasing at an annual rate of only 5.60% over the last five years. Additionally, the stock is trading at a premium compared to its peers, which may deter investors.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has gained 1.57% over the past month. The stock has underperformed the BSE500 over various time frames, including the last three years and one year, where it has generated a return of -15.97%. This underperformance, coupled with flat results in September and a low debtors turnover ratio, suggests that investors may be cautious about the company's future prospects. The rising investor participation, indicated by a 56.66% increase in delivery volume, may not be sufficient to counteract the negative sentiment surrounding the stock's valuation and growth potential.
